SPARK-GAP ADJUSTER.

Application filed April 9. 1913.

To all whom it may concern:

. over a continuous range between limits, sutficiently wide for all practical purposes.

In the accompanying drawing, Figures 1, 2, 3 represent arrangements according to the invention. and Figs. 4 and 5 show details of construction.

The sparking system usually comprises two or more electrode holders. which may be at rest or in relative motion and by means of which there are several paths across which the sparks may pass. In order to regulate the length of these sparks. the holders are mounted according to the invention on or in a deformable parallelogram, which can be manipulated so as to allow of a relative displacement of the parts. without any other movement being afi'ected.

In Fig. 1 the electrode holders 1 are mounted on bars connected to the opposite sides a, a, I), b of a jointed parallelogram. If the side a, is fixed any displacement of the side I (1 produced for example by the screw device 2 would incline the bars 1 and cause them to be brought nearer together, although still parallel. For this purpose the bars 1 may be carried in forks 3 (Fig. 4) in the sides a and b or in any Way, which allows the necessary turning motion.

Copies of this patent may be obtained for Specification of Letters Patent.

' Patented Mar. 21. 1916.

Serial No. 760.074.

The invention is applicable to electrodes formed as'cylinders. rods 01' of any complex shape. In Fig. 2 the electrodes are shown as disks I mounted at right angles to the bars connecting the sides (1 and l) of the parallelo gram.

In Fig. the bars 1 are pivoted at 5 to the fixed side a of the parallelogram but. proje t beyond it.

Fig. 5 shows a construction according to Fig. 3 in which the fixed side (1. a is in two parts carrying the axis 5, and themovable side I) is connected in any convenient manner to the disks.

Several such systems can be placed over each other. so that a large number of sparks can be obtained.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed. I declare that what I claim is:

In an electric spark adjuster. the combination with a frame comprising members hinged together and forming a deformable -parallelogn'am. bearing sockets rotatably mounted in each of the side members of the frame, and electrodes rotatably sustained by said bearing members and adapted to be rotated about their respective longitudinal axes for presenting new faces to each other. the electrodes being adapted to be moved toward and away from each other by rela tive movements of the members of the frame.

In witness whereof I have hereunto signed any name this 28th day of March, 1913. in the presence of two subscribing witnesses.

iOUIS TRONCHON.
